DL-Ethionine
CAS :DL-Ethionine is a compound that is formed when the amino acid methionine is converted to ethionine. It has been shown to induce the formation of acid in the liver and pancreas, which can lead to pancreatitis.

It is one of the most potent inhibitors of prostaglandin synthesis in human serum, but it has only moderate potency in bile and little or no affinity for fatty acids. The inhibition potential of carprofen has been shown to be stereoselective, with the (S)-enantiomer being up to 10 times more potent than the (R)-enantiomer. Carprofen is metabolized by conjugation with glucuronic acid and excreted in urine. Carprofen also has an inhibitory effect on endogenous substances such as diazepam, which may be due to its ability to inhibit CYP3A4.Formule :C15H12ClNO2Degré de pureté :Min. 95%Couleur et forme :White to off-white solid.Masse moléculaire :273.71 g/mol3,5-Di-tert-Butyl-4-hydroxybenzoic acid methyl ester
